When having certain types of outpatient surgery inside the uterine cavity some women experience heavy bleeding. The only method presently available for controlling such bleeding, short of removing the uterus, involves the placement of a balloon pressure device inside the uterine cavity. The pressure along with the patient's own natural clotting ability will generally stop the bleeding. However, this treatment usually requires at least a 24 hour stay in the hospital. The investigators are researching the use of a compound (FloSeal) already approved for use in other areas of the human body, as a method of controlling bleeding. The use of FloSeal in the uterine cavity has not yet been tested and therefore is not yet an FDA approved indication for its safe use to control bleeding from the uterine cavity. In this study, The investigators want to find out what effect(s) FloSeal has on the uterine cavity.
